CLOSRE FOR BOTTLES AND OTHER CONTAINERS Filed March 3l, 1932 Patented Oct. 24, 1933 CLOSURE FOR B-OTTLES AND OTHER CONTAINERS f James Solomon Cohen, Cape Town, .of

l South Africa Application March 31,A 1932Se1ia1`N0.` 602,291, and in Unionof South -Africa.,March 5, 1931 4 claims. (c1. 2x5- 46) The present invention consists of improvementsin or relating to closures for bottles and 'other containers and an object of the invention is to provide improved means whereby a closure 5 may be readily removed without necessitating the.

' 10 to pass between engaging surfaces of the closure and container the inner end of the tab or each of them being gripped or secured to or otherwise engaged with a surface of the closure facing into or inserted into the container and the outer end l5 being available outside the container to be pulled to remove the closure.

In one form of the invention the container has a shoulder to hold the closure in position and the closure has a surface to engage such shoulder characterized in that the tab passes between the said surface and said shoulder.

The invention is particularly applicable to the type of closure known as the crown cork closure or to similar types, which are intended to be included in the term crown cork, comprising a sheet metal capsule having a crimped or beaded edge adapted to be pressed over the mouth of a bottle, ask or other container and to be retained in position by the radial pressure of the y crimped edge againsta shoulder and the neck of the bottle or the like. Thus according to one form of the invention a crown cork for a bottle or the like is characterized by a tab of flexible material passing between the edge of the crown 35 cork and the surface of the bottle which it grips,

having the inner end gripped or secured to the inside of the crown and the outer end available to be pulled to remove the closure. The inner end of the tab may be gripped between the metal body of the crown cork and the cork insert; and the outer end may hang loosely outside the container. The capsule may easily be removed when desired by pulling the loose portion of the strip upwards and away from the container.

In order that the invention may be more readily understood a speciiic example thereof will now be described with referencel to the accompanying drawing in which Figure 1 is an enlarged perspective view of the top of a bottle with a crown'cork to which the invention is applied, and j Figure 2 is a section through the crown cork.

Like reference numerals indicate like partsV in both figures.

The bottle is provided with a crown cork 11 having the usual crimped edge 12 to secureit tothe bottle. `Within the crown cork is 'a cork insert 13 andwashers 14 and l5 ofvwaxed paper and metal foil respectively. Between the washer 15 and the metal body of the crown cork is 60 wedged one end 16 of tab 17 consisting of an oblong piece of stout cloth'y fabric e.g. drill, light canvas or the like. 'Ihe end i6 of the tab is circular and iits within the capsule where it is wedged by the cork stopper or wad 13. An adhesive may be employed between the cork and the fabric if desired. When it is required to open the bottle the capsule is removed merely by pulling the tab or nap upwards and away from the bottle. A

In order to accommodate the thickness of the fabric strip between the rim of the bottle and the side of the capsule particularly in the case where the device is applied to a capsule such as described it may be necessary to slit the side of the capsule at either side of the fabric strip as shown at 18 and 19 in order to allow a slight outward displacement of that portion of the side of the capsule beneath which the fabric strip passes.

The outer end of the tab is provided with a small i quantity of adhesive 20 along its outer edge to '80 secure it temporarily folded back over the top of the closure to enable the latter to pass through the chute of a self-feeding corking machine of existing type. When the crown cork has been applied, by pressure, to the mouth of the bottle, or other container this gummed flap can be easily detached from the top of the crown cork so as to be ready for use in removing the latter from the bottle. I u

It will be understood that, although the device has only been exemplied herein with reference to closures of the crown cork type, it is applicable to other kinds of closures in particular to metal closure capsules having a crimped or beaded edge and adapted to be pressed over the mouth of a container.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is:, 100

1. For a container, a closure having an insert within it anda tab of iiexible material comprising a portion disposed between the insert and the inner surface of the closure, another portion extending therefrom and lying between engaging margins of the container and the closure, yand a further portion extending beyond theclosure and available outside the container to be pulled for the purpose of removing the closure, and an adhesive on the outer end of the tab to secure it ,its

temporarily folded back over the top of the closure to enable the closure to pass through the chute of a self-feeding corking machine.

2. For a bottle, a crown cork having an insert of cork within it and a tab of exible material comprising a portion disposed between the insert and the inner surface of the crown cork, another portion extending therefrom and lying between engaging margins of the bottle and the crown cork, and a further portion extending beyond the crown cork and available outside the bottle to be pulled for the purpose of removing the crown cork, and slits extending inwardly from the margin of the crown cork adjacent the sides of the tab to permit such portion of the margin to yield to accommodate the thickness of the tab.

3. For! a container, a closure having an `insert of yielding material within it and a tab of flexible material comprising a portion disposed between the insert and the inner surface of the closure, another portion extending therefrom and lying between engaging margins of the container and the closure, and a further portion extending beyond the closure and available outside the concent the sides of the tab to permit a portion of the Y margin of the closure to yield to accommodate the thickness of the tab.

4. For a container, a closure having an insert Y within it and a tab of flexible material comprising a portion disposed between the insert and the inner surface of the closure, another portion extending therefrom and lying between engaging margins of the container and the closure, and a further portion extending beyond the closure and available outsidethe container to be pulled for the purpose of removing the closure, the closure being provided with slits extending inwardly from the margin thereof adjacent the sides of the tab to permit a portion of the margin of the closure to yield to accommodate the thickness of the tab, and an adhesive on the outer end of the tab to secure it temporarily folded back over the top of the closure to enable thevclosure to pass through the chute of a self-feeding corking machine.
